LAWN-SPRINKLER.

Specification of Letters Patent.

Patented Apr. 16, 1917..

Application filed May 20, 1916. Serial No. 98,829.

To all whom it may concern:

Be it known that I, FLETCHER W. YoNeE, a citizen of the United States,residing at Tampa, in the county of Hillsborough and State of Florida,have invented new and useful Improvements in Lawn- Sprinklers, of whichthe following is a specification.

This invention relates to lawn sprinklers and the like, and it has forits object to produce a new and improved nozzle of simple and efficientconstruction, whereby a whirling spray will be produced.

A further object of the invention is to produce a sprinkler nozzle ofthe character described whereby the dimensions of the spray may beregulated.

A further object of the invention is to produce a sprinkler nozzle ofsimple and improved construction by the action whereof two distinctsprays whirling in opposite directions may be formed, the coaction orintersection of said sprays serving to atomize the water, therebyproducing an extremely fine and effective liquid spray.

With these and other ends in View which will readily appear as thenature of the invention is better understood, the same consists in theimproved construction and novel arrangement and combination of partswhich will be hereinafter fully described and particularly pointed outin the claim.

In the accompanying drawings has been illustrated a simple and preferredform of the invention, it being, however, understood that no limitationis necessarily made to the precise structural details therein exhibited,but that changes, alterations and modifications within the scope of theclaim may be resorted to when desired.

In the drawings,-

Figure 1 is a plan view of one form of the device.

Fig. 2 is a vertical sectional view taken through the bulb on the line22 in Fig. 1.

Fig. 3 is a plan view illustrating a modified form of the device.

Corresponding parts in the several figures are denoted by likecharacters of reference.

The improved device in its most simple form consists of a tube 15 havingat one end an interiorly threaded socket 16 constituting a couplingwhereby it may be connected with a pipe, hose or other ductcommunicating with a source of water supply. At the opposite end of thetube 15 is formed a semispherical bulb 17 the same lying mostly to oneside of the tube which latter occupies a substantially tangentialposition with respect to the bulb. The bulb has a removable bottom plate18 which may be secured in position by fastening members such as screws19. The bottom plate 18, is provided with an upwardly bulged centralportion 23 forming a cavity 24 in the underside of the plate. The plateis centrally apertured for the passage of a screw threaded stem 25carrying an approximately conical member designated as a cone 26, theapex of which projects through an aperture, 27, in the semisphericalcasing. The stem 25 is Provided with a lock nut 29 located, adjacent tothe lower face of the bulged swelled portion of the body plate. Thelower end of the stem has a thumb piece 30 locatedwithin the re cess 24which is sufficiently large to accommodate said thumb piece when thecone is adjusted vertically; the parts being secured at variousadjustments by the lock nut 29. A guide 31 for the cone is arrangedwithin the chamber formed by the casing and the bottom plate. It isobvious that by this construction the cone 26 may be vertically adjustedto vary the dimensions of the exit 27. It will be readily seen that whenwater under pressure is introduced through the tube 15 into the chamberformed by the bulb it will, in seeking to escape through the aperture27, receive a whirling or rotary motion around the walls of the cone 26.The opening 27 is partly obstructed by the tip of the cone leaving onlya narrow annular exit, the dimensions of which may be governed byadjustment of the cone and through which the whirling body of water isexpelled in the formation of a hollow cone.

Under the modified construction illustrated in Fig. 3 the tube 15 isprovided with two separate semi-spherical bulbs 33, 34 having dischargeapertures, here designated by 38, 39, through which the apices of thecones 36, 37 project, said cones being mounted and arranged, ashereinbefore described. By this construction the water issuing throughthe apertures 38, 39 will be whirled in opposite directions, and thewhirling columns of water will intersect and be forcibly thrown againsteach other, thus producing an atomizing action, resulting in anextremely fine spray which, when the water pressure is sufficient,may bethrown a considerable distance and disseminated over a large area withmost excellent results.

A tubular nozzle, a semi-spherical casing connected and communicatingtherewith,

said casing being positioned mainly at one side of the nozzle and saidcasing having a central opening in the top portion thereof, a

detachable bottom platefor said casing, said 7 bottom plate having anupwardly 10 portion and anupwardly' extending guide, a

bulged conical member guided by the guide and having a threaded stemextending through the bottom plate, the tip portion of the coneextending into the opening of the casing, a lock nut on the threadedstem, and a thumb piece on the stem accommodated Within the cavityformed by the upwardly bulging portion of the bottom plate.

In testimony whereof I afliX my signature.
